ANTISTATIC CHAIRS

Gref is Grendene Chairs department that has been created with the strong mission to promote and guarantee safety for people exposed to electrostatic discharges in EPA areas.
Gref antistatic chairs and stools are engineered and manufactured complying the international standard IEC 61340-5-1, so that they can be used in Electrostatic Protected Areas. They are indeed an essential and irreplaceable dissipative vehicle for electrostatic charges since they perform a dual function:
– They prevent the generation of electrostatic charges on the sitting person’s body, despite one’s movements.
– They guarantee the grounding connection to the floor discharging the static electricity that may accumulate on the person’s body.

Informations

What is E.S.D.?

 
Static electricity, or triboelectric charging, is the electric charge generated on a body through rubbing.
The main factor of this mechanism is given by a transfer of electrons from one body to another. Electrostatic charge is understood to be the quantity of electricity on a body that is electrified by rubbing.
The phenomenon with which the charge is wasted or with which the charge is neutralized is defined as electrostatic discharge, that is the transfer of charges from an electrified body to another body having an opposite sign charge.

Human body can behave as a conductor and, if isolated from the floor, it can accumulated an electrostatic charge that can be damaging for the operator as for devices and production process.
Chair is a dissipative vehicle for the electrostatic charges and it is essential and irreplaceable within the antistatic equipment, in the implementation of an anti-E.S.D. system, because it performs a dual function:
1. They prevent the generation of electrostatic charges on the sitting person’s body, despite one’s movements.
2. They guarantee the earth connection through the floor discharging the static electricity that may accumulate on the person’s body.
Through Gref department, we have always been engaged in the safeguard of human being quality of life, in its work environment, and of the quality of production process. We have created E.S.D. series: swivel antistatic chairs and stools using innovative materials.
These products are engineered and developed using materials with latest generation antistatic and dissipative properties. They are specifically build to be used in specific industrial electrostatic protected environments such as in the field of: electronics, chemicals, pharmacy, healthcare, plastics, textile.
All GREF E.S.D. line antistatic and dissipative chairs and stools models have passed characterization tests and comply IEC 61340-5-1 norms.
Thanks to their ergonomic and comfort characteristics, Gref antistatic and dissipative chairs can be used in environments that are different from the above mentioned ones or in all sectors, in which an electrostatic protected environment is required (EPA areas).

Innovative materials

Always on the cutting edge in the research of innovative products that are able to contribute to safeguard both human beings’ health and a perfect operation of equipment in workplaces, GREF has developed, for its products (antistatic chairs and stools), a range of upholsteries and materials for the molding of seats and backrests, all of them with latest generation, permanent, antistatic and dissipative properties.

Fabric upholstered antistatic chairs and stools

The fabric used for the upholstery of antistatic chairs and stools is a special ESD certified fabric, which is able to optimally prevent and dissipate electrostatic discharges. This particular manufacturing allows this fabric to prevent and to dissipate the static charge generated by the operator’s body rubbing, in order to completely avoid any damage to the product during its manufacturing, as well as to the devices in the workspace and to the operator. We can then declare that ESD chairs and stools with this upholstery:

  • Are endowed with excellent, permanent antistatic dissipative qualities – IEC 61340-5-1 – IEC 61340-5-2
  • Prevent and dissipate electrostatic charges
  • Are endowed with color stability to sweat – UNI EN ISO 105-E04
  • Can be sanitized using adequate cleaning products
  • Have passed all tests that are required in Italian and international rules
  • Are flame retardant

ESD chairs and stools in polyurethane

The material used for seat and backrest has got high-level antistatic dissipative qualities, it is water-repellent and resistant to the influence of hygienic and sanitary environments (where a contamination risk exists); in addition it offers an excellent comfort. ESD chairs and stools, with integral polyurethane seat and backrest, are engineered products, designed to be used in particular industrial environments with controlled static electricity,such as chemical, electronic, pharmaceutical, healthcare sectors and in the “clean” environment of white rooms. We can then declare that ESD chairs and stools with seat and backrest in polyurethane:

  • Are endowed with excellent, permanent antistatic dissipative qualities – IEC 61340-5-1 – IEC 61340-5-2
  • Prevent and dissipate electrostatic charges
  • Can be sanitized using adequate sanitizing cleansers
  • Have passed all tests required in Italian and international rules
  • Also available in the 1IM certified fireproof version

Esd Artificial leather

Artificial leather is a highly technical, soft, completely washable and hygienic material. These characteristics combine with high electrical conductivity and fire resistance. This product therefore becomes optimal for use in the hospital sector, laboratories and industry in general.

  • Electrical resistance values –ISO 2878 method – OHMS 10 000 – 1 000 000
  • Compliance with EN ISO 1021.1 standard for fire resistance
  • Can be sanitized using specific sanitizing cleansers

We ensure a double protection!

GREF antistatic chairs are a a dissipative tool for electrostatic charges; they play an essential and irreplaceable role, as compared to all antistatic equipment, in the development of an EPA area, as they have a dual function:

  1. They prevent the formation of electrostatic charges on sitting person’s body
  2. They guarantee the grounding connection to the floor discharging the static electricity that may accumulate on the person’s body.

Ergonomics and protection!

In addition to guaranteeing high standards of safety and protection in EPA areas, Gref ESD chairs offer the highest levels of ergonomics and comfort. The chairs and stools have ergonomic seats and backrests, a wide choice of adjustment mechanisms and armrests that are available both adjustable or fixed. All this makes this ESD chair and stool line the ideal tool for long-term use in workstations, which can significantly improve the physical well-being of the user.
